title: Association of the transferrin locus on chromosome 13 with early body weights in pigs.
abstract: The effect of the genotypes of five different blood protein loci (α1B-glycoprotein, A1BG; glucose phosphate isomerase, GPI; phosphogluconate dehydrogenase, PGD; postalbumin 1A, PO1A; transferrin, TF) on early body-weight traits was studied in one large population of Swedish Yorkshire breed pigs. A highly significant association was observed, between the transferrin genotypes and the piglet body weights, at 6 and 9 weeks of age. The TF BB type pigs were heavier than those of TF AB types at 3, 6, and 9 weeks of age, by 130, 340, and 370 g, respectively. In the light of previously published data, it was discussed that TF is an additional chromosome 13 marker that may affect early body weights in pigs. The other four loci studied, located on chromosomes 6 and 7, did not show any significant effect. ZUSAMMENFASSUNG: Zusammenhänge zwischen Transferrinlocus an Chromosom 13 und Ferkelgewichten Die Wirkung von fünf verschiedenen Blutproteinloci (αB-Glykoprotein, A1BG; Glukose Phosphat Isomerase, GPI; Phosphoglukonat Dehydrogenase, PGD; Postalbumin 1A, PO1A; Transferrin, TF) auf Ferkelwichte wurde bei Schwedischen Yorkshire Schweinen untersucht. Der Zusammenhang zwischen Transferrin Genotypen und 6 und 9 Wochen Gewichten war hochsignifikant, TF BB Ferkel waren bei 3, 6 und 9 Wochen Alter um 130, 340 und 370 g schwerer als TF AB Ferkel. In zusammenhang mit früheren Studien wird TF als ein weiterer Chromosom 13 Marker für Ferkelgewicht erörtert. Die anderen vier Loci an Chromosomen 6 bzw. 7 zeigten keine signifikante Wirkung.
